To work out my intense emotions after the death of Whitney Houston, I wrote another iteration of "many 3-4, very hard questions on American History topics." In this case, they are all from (well, almost all) from the 20th century, tend to lazily in chronological order, and are I think probably harder than the last few iterations. I'll read it in the IRC either tonight or tomorrow night and then post it here afterwards.
